The racoon daemon in IPsec-Tools 0.8.2 contains a remotely exploitable computational-complexity attack when parsing and storing ISAKMP fragments. The implementation permits a remote attacker to exhaust computational resources on the remote endpoint by repeatedly sending ISAKMP fragment packets in a particular order such that the worst-case computational complexity is realized in the algorithm utilized to determine if reassembly of the fragments can take place.

CVE-2016-10396 ipsec-tools vulnerability
Title: ipsec-tools vulnerability
Summary: ipsec-tools could be made to crash if it received specially crafted network traffic.
It was discovered that racoon, the ipsec-tools IKE daemon, incorrectly
handled certain ISAKMP fragments. A remote attacker could use this issue to
cause racoon to crash, resulting in a denial of service.
Instructions: In general, a standard system update will make all the necessary changes.
